When your line (green) is consistently above the close (blue), you're beating the market. That's positive CLV — the strongest evidence of real betting edge.
A steam move is a rapid, coordinated line shift across multiple books triggered by sharp money. With full tick-level data, you can detect these signals in real time or backtest historical steam patterns.
STEAM = rapid multi-book move · RLM = reverse line movement (public one way, line moves the other)
When the majority of public bets are on one side but the line moves the other way, that's reverse line movement — a classic sharp money signal. Historical RLM data lets you backtest how reliable this signal is by league, sport, and market type.
Handle/ticket split data coming at launch. Currently available: full line movement history to derive RLM signals.
